Dominique Strauss-Kahn, the disgraced former chief of the International Monetary Fund (IMF) now facing sexual assault charges, was a frequent customer of a notorious Manhattan escort service, according to reports.

Former madam Kristin Davis, whose escort service also catered to the former governor of New York, Eliot Spitzer, told media that she provided prostitutes for Strauss-Khan in 2006 when he was running for France’s presidential nomination as a Socialist.

At that time, Strauss-Khan was not head of the IMF.

Reportedly, one of her girls griped about his aggressive behavior.

He was a client of my agency, she told The Daily Telegraph newspaper of Britain.

When men abuse women I'm no longer going to protect their identities.

Davis, who has alleged to have large pool of well-known clients, claimed that Strauss-Khan would call her directly and paid $1200 in cash for two-hour sessions in New York hotels.

He wanted an 'All-American girl', with a fresh face, from the mid-West, she said.

A girl in January 2006 complained he was rough and angry, and said she didn't want to see him again.

Davis also alleged that in September 2006, when Strauss-Kahn arrived in New York to attend a conference hosted by former US President Bill Clinton, she provided the Frenchman with a Brazilian prostitute, who later complained that he was rough.

Davis has herself served prison time for running a prostitution ring. She even ran for New York governor last year.

The Times of London reported that Strauss-Khan was referred to the New York escort service by a Bosnian prostitute in Paris named Irma Nici.

She told the Daily Mail: “Strauss-Kahn was rough and aggressive, however he maintained a certain level of decorum because he was dealing with an agency. The girls said he was pushy, overly grabby and forceful. He did not rape anyone. However, at $1,000 or more an hour, we expected the clients to behave like gentlemen, not animals.”

Nici added: “I have spent three years protecting the men on my client list - however, I will no longer protect those that abuse women.”

Separately, there are now other reports that Strauss-Khan sexually assaulted another hotel maid in Mexico.

In a book called “DSK: Secrets of a presidential contender” written by a female author using the pseudonym Cassandre, the alleged incident occurred in recent years when Strauss-Khan made an official visit to Mexico.
